New law classifies unlawful possession of catalytic converters as class E felony

Missouri lawmakers are tackling the rising issue of catalytic converter theft with the introduction of House Bill 757, aimed at criminalizing the unlawful possession of detached catalytic converters. Introduced on April 16, 2025, the bill seeks to address a growing concern as thefts of these valuable vehicle components have surged, driven by their precious metal content.

Under HB 757, possessing a detached catalytic converter with the intent to sell it—unless for legitimate business purposes or lawful reasons—will be classified as a Class E felony. This provision is designed to deter thieves and curb the black market for stolen parts, which has become increasingly prevalent across the state. The bill's proponents argue that it will provide law enforcement with the tools necessary to combat this crime effectively.

Debate surrounding the bill has highlighted concerns about its potential impact on legitimate businesses that deal in auto parts. Critics worry that the legislation could inadvertently penalize those who possess detached converters for lawful reasons, such as repair shops or individuals working on their vehicles. Amendments may be proposed to clarify these exceptions further.

The implications of HB 757 extend beyond criminal justice; they touch on economic and social dimensions as well. By targeting the theft of catalytic converters, the bill aims to protect consumers from rising repair costs and insurance premiums associated with vehicle theft. Additionally, it reflects a broader trend of states tightening regulations to combat property crimes in response to public outcry.

As the bill moves through the legislative process, its supporters remain optimistic about its passage, viewing it as a necessary step to safeguard both property and community safety. If enacted, HB 757 could set a precedent for similar legislation in other states grappling with the same issue, potentially reshaping the landscape of auto theft prevention nationwide.
